ROBERT W. MUNK, OF ATLANTA, GEORGIA, ASSIGNOR OF ONE-THIRD TO L. J. DE GIVE AND ONE-THIRD TO J. T. THOMASON, BOTH OF ATLANTA, GEORGIA.

INKING- DEVICE.

T 0 all whom it may concern:

Be it known that 1, ROBERT "W. MUNK, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Inking Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in inking rollers, and particularly to inking rollers adapted to act as a fountain roller which receives the ink in its interior and feeds the same to the periphery as the ink is needed.

The invention further comprises an inking roller in combination with a printing machine whereby the printing machine and roller may be operated so that when the type is at rest the inking roller will be inking the same, and when the type is making an impression the roller will be at rest.

An object in view is the provision of an inking roller arranged to receive ink in the interior and to feed the same to its outer surface in such a manner as to form an even distributing of the ink for use.

Another object of the invention is the provision of an inking roller and mechanism for operating the same in connection with a printing or stamping machine.

Nith these and other objects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawing: Figure 1 is a view partly in elevation and partly in section of a complete stamping machine, including the stand and foot operated parts, together with an inking roller. Fig. 2 is a view in side elevation of an inking roller with the distributing mesh and blanket removed. Fig. 3 is a detailed longitudinal vertical central section through the inking roller detached. Fig. 4 is a detailed plan view of the inking roller and operating parts.

Referring to the drawing by numerals, 1 indicates an inclosing housing or casing which covers all parts of the machine which require protection, and which do not demand to be exposed, and within the housing Specification of Letters Patent.

Patented Aug. 3, 1909.

1 is arranged a framework 2 which extends upwardly and throughout the casing to all points necessary for sustaining the parts of the machine, the parts of the machine being sustained by the framework 2. The casing 1 and framework 2 are mounted upon a stand 3 containing foot lever mechanism hereinafter described. A head 4 is provided upon casing 1 and is arranged to receive type disks 5 which are revolubly mounted in head portion 4 and may be operated or revolved in any desired way for causing any of the type on the wheels to bebrought in position for operation.

Within the boxing portion of the housing suitably supported on framework 2 is a ower shaft 6, to which shaft is fixed a ownwardly curved arm 7 which is engaged by the bifurcated u per end of an operating link 8, the said link o otaining power from any desired source, but by preference as shown in Fig. 1 being connected with a lever 9 which is pivoted at one end to supporting stand 3 at 10 and at its opposite end is retained normally in its uppermost position b spring 1 1, the lever 9 in turn being engaged y link 12 which extends to a foot treadle or lever 13 so that the lever 7 may be depressed by depressing the treadle 14 at the outer end of the lever 13.

Connected to lever 7 is a sleeve 15 that has arms 16 and 17 radially projecting upward therefrom to the outer end of whlch is pivoted a frame 18 which is adapted to carry an inking roller 19. For preventing contact of the roller 19 with the article to be printed, a guard 20 is preferably disposed in front of the roller as seen in Figs. 1 and4. Extending forward from the frame 18 is a yoke 21. An arm 22 extends upwardly from the sleeve 15 through yoke 21 and is formed with a bent end 23 through which a pin 24 is slidably passed, said pin being fixec to the outer end of the yoke 21. A thumb nut 25 is threaded into the outer end of pin 24 for the purpose of adjustment, and an extension pm 26 surrounds the in and enters between the yoke 21 and the ent end 23 so that the frame 18 with its inking roll 19 will follow the movement of the arm 7 subject to the pressure of spring 26.

The inking roller proper is constructed preferably as indicated in Figs. 2 and 3 and consists of a hollow cylinder 27 having one of its ends threaded or otherwise detachably con- Divided and. this application filed September 17,

nected as at 28 for facilitating the introduc- 1 disk 5.

'tating the distribution of the ink. Surrounding the cylinder 27 is a wire mesh cylinder 32 which is covered by a distributing blanket 33 of cotton or other suitablefabric. In the opposite end of the cylinder 27 from the removable'cap 28 is arranged a piston or plunger 34 engaged by a piston rod 35 which is passed through the hollow journal 36 of the cylinder 27. The outer end of the piston rod 35 is provided with a button or nut 37, and a spring 38 is interposed between said nut and thejournal 36 so as to normally maintain the piston rod and piston in their outermost position.

In operation indelible ink must be employed sometimes, and even with the precaution rovided in the structure just described oes not remain sufiicientlymoist, whereupon the operator will'simply press in- 'wardly upon the button or nut 37, and then release the same which will thrust theppiston 34 inwardly and cause said piston to're'turn to its outer position. This will have the effect of first forcing a comparatively large quantity of ink outwardly through the apertures 31, and then draw the same inwardly again. This will thoroughly moisten the blanket 33 and insure the even distribution of ink. The cap 28 isprovided with ajour- 'nal 36 and the said-journals 36 and 36 are mounted in suitable bearings in the frame 18. By preference I turn down the intermediate portion of the cylinder 27 as clearly indicated in Figs. 1 and 2, so that the ends of said cylinders have greater diameters than the intermediate portions so that the wire mesh cylinder may be fitted against the cylinder 27 and be flush with the end ortions and the inner surface of the edges 0 the blanket 33 rest against the end portions of the cylinder. This is of course an arbitrary feature of construction and may be varied at will. However, the wire mesh is preferable for the proper distribution of the ink, although 1 have found that by knurling the cylinder the capillary action will produce efficient result. When the cylinder 27 is knurled the wire mesh need'not be used, and when thus depending upon the knurling the grooves of the knurling are preferably out rather deep so that the projecting portions "a'nd 'grooves may act'a's'meansfor freely distributing the ink to blanket 33.

In operation when it i's'desired to ink any 'of'the type on type disk 5, treadle '14 is depressed which will cause inking roller 19 to wipe'acro'ss th'e type on the lower edge of the When the treadle is released the ink-' ing-roller 19 takes the position shown in Fig. 1. During the wiping action of inking roller 19 ink is taken off from blanket 33 as the same is saturated with ink from the interior of cylinder 27. Ordinarily the ink will flow through the various apertures 31 for keeping the blanket 33 saturated, but if for any reason the apertures 31 should get stepped up so that the ink on the blanket should become dry the same may be refreshed by pressing inward nut or member 37, which will cause ink to be forced positively out through open ing 31 and then drawn'in again'to a greater orless extent. Member 37 may be pressed by hand at any desired interval, or means may be provided for automatically forcing the same inward, together withthe piston 34 at predetermined intervals. A cam, for instance, might ee-mounted upon the machine upon which the roller'is used for at intervals pressing inward member 37. This will give a refreshing supply of ink to the blanket at intervals,and will thereby positively keep the same in the best possible conditionfor inking the type. After each refreshing the ink will continue to feed in the usual manner to the outer surface of roller 19.

The roller '19 is particularly adapted for use with a stamping machine, for instance,

a stamping machine for stamping laundry,

but it is evidentthat the same may be used for other machines within the spirit of'th'e invention.

This application is a divisional application of my former application,Serial N 0. 402,031, filed November 13, 1907, for stamping machine.
